A Proton Mail phone number for verification is a United States mobile number that receives the Proton Mail SMS code for you, so your own number stays private. Proton Mail is a secure email service focusing on privacy and encrypted communication.
Proton Mail requests a phone number during registration or when suspicious activity is detected, sending a code via SMS for verification. SNSPhone numbers are real US carrier numbers, not VoIP, and one Proton Mail verification costs $0.45 with a 20 minute window and an automatic refund if no code arrives.

Proton Mail may prefer real mobile numbers to verify user authenticity and limit abuse of anonymous accounts.
Check your spam folder if the code does not arrive, as some SMS filters may delay it.

Step by step
The whole job takes about two minutes once your account has credit. Here is every step, from signup to a secured Proton Mail account.
Press Sign up. Your browser makes an access token; save it as a file or copy it. No email or phone number is needed.
Open Credits and top up with USDT, USDC, BTC, ETH, BNB, SOL or LTC. The minimum is $30 ($20 in lower-income countries), and the first top-up from $100 gets a bonus.
Open New verification, pick Proton Mail and confirm. A US mobile number shows at once, with a 20 minute window.
Choose United States (+1) in the Proton Mail form and type the 10 digits. Ask Proton Mail to send the code by SMS, not by a call.
The SMS shows in your console within moments, with the code picked out and a copy button. The page refreshes by itself.
Type the code into Proton Mail, then add your own email or an authenticator app in the Proton Mail settings so later sign-ins do not depend on the number.
Ask Proton Mail to send the code again from its own screen. If nothing arrives in the 20 minute window, the verification closes and the full price returns to your credit by itself.
Cancel the verification while it is waiting: the full price comes back at once. Start a new one and you get a different US number.
Press Another code in the console and ask the service to send a new SMS. It reaches the same number inside the window, free.
A verification number is not yours after 20 minutes, so add your own email or an authenticator app to the account before the window ends.
More answers about numbers, refunds and rentals are on the FAQ page, and the reasons apps refuse VoIP are explained in the non-VoIP guide.
